Terraria House Building Guide: Requirements, Materials, & NPC Housing

Terraria isn’t all about digging into the earth, beating bosses, and gathering items. The title is still a sandbox game, and that means there's plenty of building to do as well! For players looking to make a shelter of their own, or even an extra house to bring in important NPCs, here's our guide on building a house in Terraria.

Building Houses in Terraria: An Overview

Terraria introduced the housing mechanic in version 1.1. Note that a house in Terraria can be nothing more than a box if it meets the correct requirements. However, you can also let your creative side loose in this game with the right materials and for as long as you like - meaning there's plenty of room to build some awe-inspiring constructions.

What Are the Minimum Requirements for a House in Terraria?

A space in Terraria can’t be called a house until it meets specific prerequisites. These minimum requirements are as follows:

• A total of 60 tiles (10 tiles high x 6 tiles wide, including the ceiling, floor, and walls)
• One light source
• One table or flat-surface item
• A chair or comfort item
• An entry point (e.g., door, gate, or trap door)

Check the housing menu by opening the inventory and clicking the house icon when building the space. Doing so lets the game check if the house you’re building is valid for an NPC to move in or not. If it’s the latter, a text will appear on the bottom-left corner of the screen telling you what’s lacking. Note: An NPC home can’t exceed 750 blocks. The house becomes invalid if it exceeds this point.

Building a House for NPCs (Requirements & NPC Preferences)

Although it’s not immediately noticeable to players, NPCs have a hidden happiness meter. A “happy” NPC will have lower prices for the goods they sell than usual. Plus, the Tax Collector NPC can collect more tax from happy NPCs than those who aren’t content with their living spaces. Optimize an NPC’s happiness level by placing them in appropriate locations in your town. Follow these factors to ensure you’re placing those characters in their preferred areas:

• An NPC must be in a Liked Biome
• An NPC must be within 25 tiles of a Loved or Liked NPC
• An NPC must be living alone (no other NPC in a closed 25-tile space)
• No other NPCs within 120 tiles

Tip: Open the inventory, click on the housing menu, then click on a specific NPC if you want to move that character to a different house. Here’s a list of preferences of Terraria’s different NPCs to help you optimize their placements:
